Ectatomma:

Ectatomma is a Neotropical genus of ants in the subfamily Ectatomminae. The genus contains 17 described extant species and one extinct species.[2]



Distribution and habitat[edit]

Ectatomma is one of the most common genera in the Neotropical region,[3] with most species being South American in their distribution, but others can be found in Central America as well as sparse populations in the Caribbean. Ecatomma may be found in rainforests, savannas, dry environments and cultivated areas.[4]

Ectatomma is a genus of relatively large ants with large convex eyes high up on the head, a strongly convex mesonotum bordered by suture lines, a strongly upright petiolar node, and a distinct constriction separating abdominal segments 3+4. The two species of most concern for accidental introduction are E. tuberculatum (Oliver) and E. ruidum (Roger). Both species are widespread across their native Neotropical ranges, and the latter is also known from the Galapagos. Both species have also been intercepted at US ports of entry, along with several other of their congeners. Colonies of Ectatomma tuberculatum were intentionally introduced to Texas in 1904 as a biological control agent for weevil pests, but apparently did not survive past 1905 (Weber, 1946). Details of both species concerning their biology and natural histories were comprehensively chronicled by Weber (1946).

Diagnosis of worker among Antkey species. Antenna 12-segmented. Antennal insertions at least partly covered by frontal lobes. Anterior margin of clypeus not denticulate. Eyes medium to large (greater than 6 facets); situated at or above midline of head; strongly convex and protruding. Mandibles triangular. Mesonotum forms a prominent convexity bordered by distinct suture lines. Hind coxae lacking dorsal spine. Tarsal claws with subapical tooth. Waist 1-segmented. Petiole narrowly attached to gaster; conspicuous posterior face. Gaster armed with sting. Abdominal segment 4 lacking deep longitudinal furrows; distinct constriction between abdominal segments 3+4. 

Among intercepted ants, Ectatomma species are most likely confused with Gnamptogenys porcata and Gnamptogenys triangularis, but can be readily distinguished by the distinctive mesonotal convexity, the lack of a dorsal spine on the hind coxae, and the lack of deep longitudinal furrows on abdominal segment 4.

Genus 6. ECTATOMMA HNS .

Head subquadrate; antennae inserted forwards on the face at the base of the clypeus, 12-jointed in the female, 13-jointed in the male; eyes ovate and very prominent, placed a little behind the middle at the sides of the head; maxillary palpi 2-jointed, labial palpi 2-jointed; mandibles triangular, with one or two minute teeth near their apex. Thorax: wings with one marginal and three submarginal cells, the second submarginal cell receiving the recurrent nervure near its base; legs elongate, the spur which arms the apex of the intermediate and posterior tibiae simple, that at the apex of the anterior pair pectinate within. Abdomen: the node of the peduncle incrassate, a deep strangulation between the first and second segments.
